MANY MANY Thanks for the tip and infos.
I confess i'm still a bit loss but immensely appreciate your help and will decide / have final info but the end of the week.
Alternatively, or rather in addition i have a PAR (or Europe) to NYC (via any route) to do "by" Sept 10.

Also quick trip / 2-3 days on site. Don't care about route (even if CDG>SFO then SFO NYC > NYC CDG) thought i need something reasonnable though
Maybe promo or deals around.
